In recent years the circumpolar region has emerged as the key to understanding global climate change. The plight of the polar bear, resource extraction debates, indigenous self-determination, and competing definitions of sovereignty among Arctic nation-states have brought the northernmost part of the planet to the forefront of public consideration. Yet little is reported about the social world of environmental scientists in the Arctic. What happens at the isolated sites where experts seek to answer the most pressing questions facing the future of humanity? Portraying the social lives of scientists in Resolute, Nunavut, and their interactions with logistical staff and Inuit, Richard Powell demonstrates that the scientific community is structured along power differentials in response to gender, class, and race. To explain these social dynamics, the author examines the history and vision of the Government of Canada’s Polar Continental Shelf Program and John Diefenbaker’s “Northern Vision,” combining ethnography with wider discourses on nationalism, identity, and the postwar evolution of scientific sovereignty in the High Arctic. By revealing an expanded under­standing of the scientific life as it relates to politics, history, and cultures, Studying Arctic Fields articulates a new theory of field research.
